Penguin Bank

Penguin Bank is the name given to a now-submerged shield volcano of the Hawaiian Islands. Its coral-capped remains lay immediately west of the island of Molokaʻi under relatively shallow water as shown on a bathymetric map to the right of the text of this Wikipedia page. Penguin Bank was one of the seven principal volcanoes (along with West Molokaʻi, East Molokaʻi, Lānaʻi, West Maui, East Maui and Kahoʻolawe) that formerly constituted the island of Maui Nui. The volcano is part of the Hawaiian-Emperor seamount chain. The last eruption is unknown.
